President Donald Trump should tell Congress he will "walk away from the frigging table" if they attempt to railroad him on healthcare, according to South Carolina Republican Sen. Lindsey Graham.

"Here's what I'd do if I were President Trump. Say: 'I've got a view of healthcare, tell me your views, I'm going to try to work to get to yes with as many people as I can realizing almost no Democrats are going to help,'" Graham said in an interview with Politico Wednesday. "But just say this: 'I'm not making a deal for a deal's sake.'"

Graham added that if Congress attempts to rush him on the bill, Trump should say, "I'm not going to give into demands by members of Congress or the Senate if I don't believe it's in the interest of the American people and just walk away from the frigging table."

Trump warned Republicans in the House of an electoral "bloodbath" if the plan to replace Obamacare falls apart, according to CNN. Trump reportedly made the remark during a meeting with House GOP leadership, according to an unnamed person present at the meeting. Other sources claim Trump agreed to back the plan "100 percent."

The U.S. Conference of Mayors, led my Oklahoma City's Mick Cornett, announced its opposition to the bill Wednesday, in a statement to News 9 in Oklahoma City.

"Upon review of the recently released GOP Affordable Care Act repeal and replacement plan, we are very concerned that the new bill has been issued without knowing how much it will cost or how many people it will cover," reads the USCM's statement. "By skipping the major step of having the plan scored by the Congressional Budget Office before the committees begin their consideration, we are left in the dark as to how this plan will impact not only our residents, but also city budgets."

The group add later that "the bill slashes state funding for Medicaid and states will be forced to end coverage and eliminate healthcare services for low-income seniors, people with disabilities, children, and working families."
